Claims. (Cl. 144-13) This invention relates to a machine for manufacturing construction units or the like, and more particularly to a machine for securing shakes or shingles to a backing or baseboard.

An object of the present invention is to provide a machine which removes backing or baseboards, one by one, from a supply source and applies adhesive to selective portions of the backing board, then after application of suitable shakes or shingles to said backing board advances the construction unit. to a heating unit wherein the adhesive is dried and the shakes become permanently secured to the backing board.

Another object of the invention is to provide an improved machine of the above type in which the various steps of advancing the backing board from a supply source, and applying adhesive strips to selective portions of the backing board, etc., are accomplished with an unusual degree of dispatch, so that the backing board containing adhesive strips may be further supplied with shakes, heated to dry the adhesive and discharged from the machine at a relatively rapid rate as compared with existing machines for the same purpose.

Another object of the present invention is to provide a machine for making shingle panels characterized by its structural simplicity, the ease of assembly of its parts, its strong and sturdy nature and its low manufacturing cost,

Other features of this invention reside in the arrangement and design of the parts for carrying out their appropriate functions.

Further objects of the present invention and certain practical advantages will be referred to in or will be evident from the following description of one embodiment of the invention, as illustrated in the accompanying drawings, in which:

crore describing in detail the herein disclosed em- J-oolment of the invention, it is to be understood that the present invenLon is not limited to the structural details or the particular arrangement of parts herein shown, as devices embodying the present invention may take other forms. lt also is to be understood that the phraseology and terminology herein used are for purposes of description and not of limitation, as the scope of the present invention is denoted by the appended claims.

It is believed that a preliminary explanation of the successive steps in the 'present machines function will facilitate and expedite an understanding of the various machinesections and their cooperation in carrying out the objectives of the invention.

Referring to Figs. 1 and 3, I have shown a stack of backing boards 10 which are used to build the prefabricated construction units as seen in Fig. 6. The backing boards, as seen in Figs. 6 and 7, are used to secure a course of shingles or shakes 11 thereto in forming a prefabricated construction unit or shingle panel. ln operation, the machine removes the lower backing board from the bottom of the stack i2 at the rear of the machine and moves the backing board forwardly through suitable stationary feed rollers 13 and 14 to a pair of adhesive application rollers 15 and 16. The rollers l5 and 16 apply adhesive to the upper surface of the backing board while it is in transit toward the front portion of the machine wherein the shakes or shingles are applied thereto. Following its passage under adhesive application rollers 15 and 16, the backing board travels beneath a pair of spaced adhesive spreaders 17 and 18, which are effective in smoothing out and spreading the adhesive strips laid down by adhesive applying rollers 15 an 16 respectively. That portion of the machine described above is enclosed within the housing 29, as seen in Fig. 5. Following the operation of spreading the adhesive strips, the backing board is presented at the left of the operator, as seen in Fig. 5. The operator removes the backing board from beneath the housing 2t) and places it upon a rotatable drum 21, after which he places a course of shakes or shingles upon the adhesive containing surface of the backing board, as seen in Fig. 5. When the shakesA have been applied to the backing board, the drum 21 is rotated into the position shown in Fig. 2a wherein the backing board and its associated shakes are maintained in a substantially horizontal position. An electrode heating `press 22 is then lowered into contact with the outer surface of the shakes and thereby dries the adhesive to form a permanent bond between the backing board and the shakes. Upon further rotation of drum 20, a rotating saw blade 23, as seen in Fig. 2, trims the outermost edge of the shakes just prior to removal of the construction unit from the drum 2.

Referring now to Fig. l, wherein I have shown an isometric exploded view of the various essential components of the machine for purposes of more clearly illustrating the construction of the machine and to facilitate understanding the operation of the machine. it will, of course, be understood that the machine includes a suitable supporting frame shown in part at 25 to which all of the parts are properly secured. Since the frame forms no part of the invention, it has been omitted, for purposes of clarity, to a large extent from the drawing. At the rear or left end of the machine, as seen in Figs. 1 and 3, a suitable hopper comprising upright angle irons 26, is supported in any convenient manner. The hopper, as seen in Fig. 2, is arranged to contain a supply of backing boards 10 in the form of a stack which rests upon a plurality of longitudinally disposed rollers 2S.

Means are provided for successively removing the back ing boards from the hopper and transferring them forwardly of the machine. The backing board transferring means include a feeder conveyor 3G) which is slidably mounted on the machine frame and actuated by a pusher arm 31 which is connected to feeder linkage 32, as seen in Figs. l and 2, and in turn actuated by clutch lever 80 as hereinafter described. When the operator pushes clutch lever S the feeder linkage 32 actuates the feederconveyor in such a manner that the feeder-conveyor is moved under the stackrof backing boards until the upstanding hook portions 30a provided at the end of the feeder-conveyor 30 engages the outermost end of the lowermost hacker hoard and moves it forwardly of the machine toward the first pair of feed rolls 13 and 14. It will be understood that as the cycle of the machine is completed, the feeder linkage 32 and its associated feeder-conveyor return to the prime position. as lshown in FigL l." The upstanding hook portions 30a have a thickness which is less than the thickness of one backing board so that no more than one hacker board will be engaged bv the hooks during a cvcle of the machine. A stop bracket 26a prevents the stack of hacker boards from moving forward, as a unit. upon removal of the bottom board bv means of the feeder ccnvevor. The stationary feed rollers 13 and 14 receive the forward end of the backing board as it is advanced bv the feederconveyor 3i! and transfer it forwardlv toward the adhesive auplicafing apparatus. The lowermost feed roller 13 is rotatably secured beneath the guide rail 34 and is driven by a horizontally disposed shaft 35 which is suitably journalled to the machine frame. The shaft 35 is provided with a sprocket 36 which is driven by an endless chain 37 which in turn is driven bv a suitable drive motor hereinafter described. The uppermost roller 14 is also driven by means of a shaft 3S which is suitably journalled on the machine frame. Drive chain 37 engages a sprocket 39 located at the outer end of said drive shaft and thereby drives the upper roller 14. The upper roller 14 is rotatably contained within a suitable cover 40 which isrpivotally secured by links 41 to the frame. The tension between rollers 13 and 14 may be controlled by the tensioning mechanism 42 which includes an adjustable compression spring 43.

A circular saw blade 44 projects upwardly through guide rail 34 to an extent wherein it provides a groove in one edge of the backer board as it is fed forwardly through feed rollers 13 and 14 to provide a break-off line in the backer board which aids the consumer in aligning the panel during its installation. The saw blade 44 is driven directly by its own motor 45.

Means are provided for coating the upper surface of the backing boards with a pair of spaced strips of adhesive material. Said means includes the aforementioned adhesive applying rollers and 16 which are suitably mounted so as to have a portion of their outer periphery extend into an adhesive supply contained in an adhesive pot or container 46 which is fixed tothe machine frame by connecting members 47 and 48.y The adhesive applying rollers 15 and 16 are driven by means of shaft 15a and drive pinion 15b which are driven by continuous chain 37. A stationary feed roller 49, driven through chain 37, pinion 49a and shaft 4917, is located directly beneath the adhesive application rollers 15 and 16 and aids in transferring the backing boards forwardly of the machine past the rollers 15 and 16. It will be noted that the adhesive container 46 is substantially rectangular in shape and contains two slots to receive the applicating rollers 15 and 16. The flow of the adhesive onto the outer periphery of the adhesive applicating rollers is regulated by wing nuts 50 which cause members 51 to pivot about 52 andfpull or push ow regulating bars 53 to and from the outer periphery of the applicating rollers. Regulating bars 53 extend beneath the container 46 and are associated with the adhesive applicating rollers 15 and 16 as a zone directly beneath the lower end of the slots inthe container 46. It is to be understood that the stationary roller 49 continues to move the backing board after it has left feed rollers 13 and 14. As the backing board is transferred forwardly of the machine by the roller 49 it is fed onto the stationary feed roller 55 above which are mounted the two adhesive spreader rollers 17 and 18 which are adapted to uniformly spread the adhesive deposited by the adhesive applicating rollers 15 and 16. The spreader rollers' are mountedron a suitable frame 56 and 57 respectively which pivot about shaft 5S. Shaft 53 also contains a pair of Scrapers 59 and 60 which are adapted to keep the spreader rollers 17 and 18 free from ahesive and fibers from the backing board. The shaft 53 has drive pinions 61 and 62 rigidly secured thereto which are adapted to drive the spreader rollers 17 and 18 by means of continuous chains not shown, which engage the pinions 63 and 64 respectively secured to said spreader rollers. The Scrapers 59 and 69 are mounted on upstanding arms 65 and 66 which are in turn pivotally secured to shaft 58. In operation the Scrapers 59 and 60 and their associated arms are lowered into a position wherein the outer cutting edges of the blade are positioned very close to the outer periphery of the spreader rollers 17 and 18 so that any excess glue or other material from the backing boards will be immediately removed therefrom. The outer end of shaft 58 has aflxed thereto a sprocket 67 meshing with a driven chain 68 which passes around a fixed sprocket 69 secured to the shaft 7) of roller 55. ShaftA 70 is driven by means of endless drive chain 37 and sprocket 71. In this manner shaft 58 is continuously driven in rotation While the machine is operating and thus imparts rotative movement to the spreader rollers 17 and 18 by means heretofore described. After the adhesive strips have been uniformly spread by the spreader rollers, the backing boards continue to be transferred toward the forward end of the carriage by means of stationary feed roller 55. The forward end of guide rail 34 is provided with a plurality of rollers 72 which are adapted toreceive the backing boards and facilitate their removal from the guide rail 34. `A motor 73 is in driving engagement with a drive spocket 74 which in turn drives the sprocketsat the outer ends of the respective driven members of the machines Vas heretofore described, by means of endless drive chain 37. As previously mentioned, the forward end of the guide rail 34 is contained within housing 20, as seen in Fig. 5. The operator has access to the backing boards contained on the forward end of the guide rail via space 75 in the housing. Thus, as each backing board reaches the forward end of the guide rail 34 the operator removes it therefrom and places it on the rotatable drum 21, and thereafter places a course of shakes or shingles 11 upon the top surface of the backing board, as seen in Fig. 5, in bonding relation with said backing board.

Referring now to Figs. 2, 2a and 5, wherein 1 have shown the apparatus for revolving the drum 21. This apparatus lis contained Within the housing portion 20a as seen in Fig. 5. The drum 21 is octagonal in shape and each face thereof is adapted to receive a backing board 10. The bottom edge of each face is provided with a member having an upstanding flange 76 which locates and supports the lower edges of the shakes 11. The upstanding ange portion 76 is spaced some distance below the lower edge of the backing board so that the bottom of the shakes extend somewhat below that of the backing board 10. The driving mechanism for actuating the present machinery includes a clutch lever 80 which the operator controls with his foot. Upon pressing the clutch downwardly, a shaft 81 is caused to rotate and thereby pivots a belt tightening boom 82 which has secured thereto a cam follower 83 and cam followervarrn 84 which become disengaged from a notch 85a in cam 85. The belt tightening roller 86 is pressed against belt 87A and the Vincreased pressure or tension in the belt causes the main drive wheel 88 to be turned due to the increased friction on the hub 89 of drive rod 90 which is connected by means of suitable sprockets 91 and belt 92 to a driving motor, not herein shown.

The main drive wheel 88 rotates drive shaft 93 which has rigidly secured thereto a driving sprocket 94 which by means of a continuous chain drives a secondary sprocket gear 95 which is rigidly secured to a driven shaft 96. The belt tightening boom 82 also operates a brake 97 which engages main drive wheel 88. The brake 97 becomes disengaged from the drive lwheel 88 upon actuation of clutch 80. The driven shaft 96 has rigidly secured thereto a drum activator cam 98. The drum activator cam 98 is continuously driven in rotation While the drive shaft rotates. A cam follower 99 engages the periphery of drum activator cam 98 and through suitable linkage .100 causes rotation in the drum 21. The linkage 100 is provided with an outstanding pin 101 which engages a suitable ratchet surface 102 provided on the inner periphery of the drum 21 in such a manner as to rotate the drum enough to present a new face during each operation. After the cam linkage and outstanding pin 101 have rotated the drum 21 through one-eighth of a circle (since the drum here is octagonal in shape), a coil spring 103 causes the upstanding arm to return to the position shown in Fig. 2, wherein it is in a position to further actuate and rotate the drum. In other words, the upstanding pin 101 forms a drum activator which rests in a notch of ratchet 102 on the inside periphery of the drum 21. When the cycle of driven shaft 96 begins, the drum actually makes one-eighth of a cycle for each cornplete cycle of shaft 96.

The electrode press 22 is positioned above the drum 21 and its purpose is to quickly dry and render the adhesive between the backing board and the course of shakes dry and hard to thereby form a permanent bond between the backing board and shakes. The electrode press comprises a plurality of spaced electrodes which form pressing bars 105 which are contained within the housing 22 and supported by suitable frame members 105, shown in part in Fig. 2. The electrode press is disposed at a distance above the drum and as the drum rotates on its axis, the electrode press is brought successively into peripheral engagement with the outer surface of the shakes in such a manner that the electrodes or pressing bars S extend parallel to and in alignment with the strips of glue contained between the backing board 10 and the course of shakes 11.

Means are provided for raising and lowering the electrode press with each revolution of driven shaft 96. Said means take the form of a pair of spaced cams 107 which are rigidly secured to the driven shaft 96 and engage press actuating brackets 108 which are of U-shape and are suspended from the electrode press by means of rods 169. Each cam works against a coil spring 110 which constantly urge the electrode press into its upper position, as shown in Fig. 2. The coil springs 110 are contained on the rods 109 by means of an enlarged end portion 109g. The rods 109 extend freely through a bracket 111 which is rigidly secured to the frame of the machine. It will be understood that the electrode press 22 has substantially the same length as the rotating drum 2l and extends at least the full length of each of the backing boards 10 contained on the drum 21. The outermost shake, or that which is shown at the left end of Fig. 5, is trimmed by means of saw 23 at the instant the drum 21 again rotates the shake and its associated backing board following an application of heat from the electrode press 22. A suitable switch on the side of the drum rotating cani trips a timer switch for a generator, not shown, which provides power for the electrodes 105 in the electrode press 22.

The rotating saw 23 is connected to a boom 112 which raises and lowers the saw by means of a roller cam follower 113 which engages the outer periphery of cam 114 which is in turn rigidly secured to driven shaft 96. The saw lift boom 112 is pivotally connected by means of shaft 113 to the frame of the machine, not herein shown. The motor, not herein shown, for driving saw 23 is mounted on the saw lift boom 112 and continuously drives the saw 23 while the machine is in operation. A vacuum funnel 114 is also mounted on the saw lift boom by suitable means not herein shown and moves with the saw in response to actuation by boom 112.

Fig. 4 shows a somewhat diagrammatic view of the means employed for rotatably mounting the drum 21 on the frame of the machine. The drum 21 is supported on shaft 96 by means of a plurality of radially extending spokes, not herein shown, which extend from the shaft 96 radially outwardly and terminate around the circumference of the drum 21. Shaft 96 is supported by suitable bearings 120 and 121 to the frame 122 of the machine. A housing 20a covers the drum and is secured to the frame at its lower end.

When one cycle of the machine (which is measured by a complete rotation of driven shaft 96) is completed the roller 83 on belt tightening boom 82 drops back into the notch 85a on cam 85, thus loosening belt tightening roller S6 from drive belt 87 and allowing the brake 91 to be forced against the main drive wheel 8S by resilient means, not herein shown, to stop the operation.

In further pursuance of the description of the mode of operation of the present apparatus, it will be understood that upon pressing the clutch lever the main drive wheel 8S is driven by means of belt 87 which is connected to a driving motor, as heretofore described. The main drive wheel 88 drives shaft 93 which drives shaft 96. Upon rotation of driven shaft 96, cam 98 causes the rotatable drum to index. Since the drum is octagonal in shape and presents eight faces, it will be understood that the drum indexes by making an eighth of a cycle for each complete rotation of the driven shaft 96, As the backing board containing a course of shakes reaches a substantially horizontal position as seen in Fig. 2a, the electrode press 22 is caused to be lowered by means of cams 107 mounted on driven shaft 96, as heretofore described.

During the rotative progress of the rotatable drum 21 ample time lapses while the backing board and its associated shakes are maintained in a horizontal position, as seen in Fig. 2a, for the heating eect of the electrode press to cause the desired drying of the adhesive and the latter therefore is in suitable condition for adhesion of the course of shakes to the backing board as already de scribed. The electrode press is brought successively into engagement with the outer surface of the shakes to thereby dry, through the application of heat, the adhesive material between the backing boards 10 and the course of shakes 11. After the press holding cams 107 allow the press holding brackets 108 and their associated rods to rise, the drum 21 begins to rotate or index to discharge the backing board and associated course of shakes. As the drum indexes, the trimming saw 23 is activated by the saw lift boom 112 into the position shown in Fig. 2 wherein it trims the edge of the shakes along a desired line.

It will be noted that cam S5 has connected thereto suitable linkage 116 which is connected to the pusher arm 31, shown in Fig. l, which actuates the feeder conveyor 30. Therefore, it will be understood that upon actuation of the clutch lever 80 and release of the cam roller follower 83 in the notch 85a in cam S5 the feeder linkage 32 causes a new backing board to be moved forward by the feeder conveyor 30 into the stationary feed rollers 13 and 14 for the application of adhesive strips, as heretofore described.

Thus, for each construction unit which is heated and dried by the electrode press a new backing board is advanced to the forward end of the guide rail or the area adjacent the operator where he may place it upon the cycle.

The structural lunits manufactured bythe present ma chine comprise a baseboard ina row or course of shakes or shingles 3l1 which are applied to the baseboard so that the ends of the shingles project a substantial distance beyond the upper and lower edges of the baseboard. The ends so projecting are arranged in a straight line as illustrated in Figs. 6v and 7. The shingles 11 can be of random widths and irregular lengths, if so desired, and each shingle is attached to the baseboard by means of the adhesive materials applied in accordance with the present invention.V

In applying the multiple shingle construction units to a Vwall or roof 139, as seen in Fig. 8, the construction units are laid up in a slightly overlapping relation. The baseboards 10 of the course being laid ush against the wall or roof surface in such a manner that the course of shingles being laid overlap the ends of the shingles of the course immediately below so that the shingles of the course being laid extend over and cover the upper end of the shingles and baseboard of the lower course of shingles therebelow. When so arranged, the construction units,

are secured in position by the simple expedient of driving nails or other fastening means'through each construction unit and into the surface of the wall or roof. Thus, by

lhaving the baseboard secured flush to the wall or roof and the lower ends of the shingles of one course overlapping the top ends of the shingles of the course immediately below a highly watertight sheathing is provided.

In view of the foregoing description, taken in conjunction with the accompanying drawings, it is believed that a clear understanding of the construction, operation and advantages of the -device will be quite apparent to those skilled in this art.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patentris: v
